after i got over my confusion, i took a closer look. in the post in question, gary links to a column by amos brown as proof that the infamous anti-dickerson mailers were targeted at white voters. of course, the column itself doesn't say that. gary's evidence is at best circumstancial; it surely doesn't prove his point. but anyway...
in the comments under that post, known homophobe jocelyn-tandy adande called wilson "punk46201". wilson objected, because "'punk' is a well-known offensive term used against gay males", and repeated the allegation (which he's made several times before) that jocelyn recently "screamed FAGGOT at me after a political event!"
a regular commenter called indyernie responded that wilson should get over it because "I'm sure Jocelyn isn't the first to call you a faggot." then gary responded, denying that punk is an antigay slur and threatening, "Keep it up and you will be barred from commenting further on this site." so whether gary actually did (or even can) ban wilson, he definitely threatened to do so.
so i went to urban dictionary, perhaps the best site on the net for looking up slang. there are currently 145 definitions up for "punk", the majority of which are white kids discussing "punk rock" and arguing whether bands like green day and good charlotte are "punk" or not. these definitions, taken as a whole, are an unintentionally hilarious peek into music snobbery, as various people try to prove that they're better (or at least "more punk") than the other posters. but i think we can all agree that jocelyn wasn't saying that wilson is a punk-rocker, so let's ignore all that silliness.
scroll down to definition #8 and we find this:
Originally, jail lingo for a subservient, cuckolded inmate indebted to another for protection and in return obliged to perform favors both of a sexual nature and otherwise.
i'm not sure this person knows what "cuckold" means, but that does sound like an antigay slur to me. moving on to page 2 of definitions, #s 15 and 18 have antigay connotations. on page 3, #s 21, 23, 24, 27, and 30 all list antigay connotations. and so on. in summary, "punk" is disparaging prison slang for a "bottom": the catcher, not the pitcher.
i posted a comment pointing this out, and gary replied that "It's quite a stretch when you have to look that deep into an obscure dictionary to get that kind of a meaning out of the word." (which is humorous considering how much he had to stretch for in his post.) so i looked it up on merriam webster. look at definition 3c: "slang : a young man used as a homosexual partner especially in a prison". encarta, too, and also dictionary.com.
clearly, no matter what gary says, "punk" is an antigay slur (when not referring to punk rock or those who listen to it), and given what we know about jocelyn-tandy's views on homosexuality, that is obviously what she meant. it's not surprising that commenters on a right-wing blog would gay-bash like that, but considering that gary himself is gay (and a big supporter of lgbt issues) it's disappointing to say the least that it goes on at advance indiana... and that gary is apparently now more likely to side with the gay-bashers than against them, to the point that he would threaten someone with banishment for even bringing it up.
as for whether gary actually has banned wilson, or whether he is even capable of doing so, i don't know. (i'm inclined to believe that he can't really ban anyone per se, though if he wanted to be really anal about it [excuse the pun], he could manually delete any of wilson's comments as soon as he discovers them.) ¶
